Winches Marotechniek developes, designs and produces electric, hydraulic and pneumatic winches up to a capacity of approximate 100T depending on the operation and application with or without controls.
Beside our range of standard winches we can offer you a broad range of experience in client specific solutions where we will find, together with you an economic, technical and problem solving solution. We develop in SolidWorks 3D CAD software and produce, sand blast, coat and test at our own production facility. All welding is being executed according DNV NEN EN ISO 15614-1:2012 / AWS D1.1:2010 ASME IX:2013. When requested we can deliver any winch under a witness load test or full certification by a notified body (NoBo) such as DNV/GL, B.V. or LR. Please inform us your need!

Pump Drives Marotechniek develops, designs and produces, high efficiency permanent magnet, direct drive and 4-pole electric dredge pump drives for submersible (IP68) use.
Our products are commonly used in the dredge sector, for example on profile dredgers, Trailing Suction hopper dredgers and Cutter dredgers. As a specialist in client specific solutions we use only rotor and stator sets from renown European Electric motor fabricators and we produce the solid housings, flanges and terminal boxes in- house. All delivered motors have a full load test. Marotechniek have recently developed a new, groundbreaking electric underwater motor, based om Permanent Magnets Technology. The motor features built-in ‘permanent magnets’, eliminating the need to magnetise the rotor. Elimination of reactive current reduces required amperage, leading to higher efficiency. Overall, the pump assembly is 2-3% more efficient than traditional three-phase current sets and the unit is much more compact and lightweight, with less cabling required. In recognition of its efficiency, the E-motor has been awarded with the Super Premium Efficiency IE4 notation. Prior to introduction, the E-motor successfully completed extensive testing on a sand dredger. When requested we can install and deliver with or without controls and commissioning.
